Cap fasteners are the best way to install roofing underlayment, and the STINGER CN100B pneumatic cap nailer helps contractors install better—quickly, efficiently, and safely. The intuitively-designed tool fires 5 cap nails per second when using proper PSI and holds 200 caps and 200 nails which makes for fewer reloads.

-360° tool-free exhaust

-Holding capacity of 200 caps and 200 nails
